Abstract
A hydrothermal liquefaction (HTL) system has a biomass slurry flow path with a first pump and a first heat exchanger network downstream of the first pump. The first heat exchanger network includes plurality of heat exchangers in a parallel, series, and/or series-parallel flow arrangement. The biomass slurry flow path extends through cold flow sides of the heat exchangers of the first heat exchanger network. The biomass slurry flow path includes a second pump downstream of the first heat exchanger network, and a second heat exchanger network downstream of the second pump. The biomass slurry flow path extends through cold flow sides of the heat exchangers of the second heat exchanger network. A hydrothermal liquefaction (HTL) reactor is downstream of the second heat exchanger network. Heat transfer liquid in a heat transfer liquid circuit flows through hot flow sides of the heat exchangers of the second heat exchanger network.
